zcleims." (01. -109) Our invention pertains to the'construction of cradles,.the structural design being specifically adapted for use with cradles describedqin our previous application on Cradles, Serial Number 21,938, filed on'April 19, 1948. As pointed out in said application, the cradle of our invention includes electromagnetic means to impart to the cradle a continuousQrocking motion. The structure contemplates upright standards on a horizontal base and cord suspension of the cradle reference 'to the accompanying drawings in s which:

Figure 1 is a perspective view of our cradle; Figure 2 is a longitudinal, sectional view thereof, somewhat enlarged, on line 2-2 of Figure 1;

Figure 3 is a sectional view on line 3-3 of Figure 2;

Figure 4 is a vertical, sectional view on line 4-4 of Figure 2;

Figure 5 is a vertical, sectional View on line 55 of Figure 2;

Figure 6 is an enlarged, side elevation of a detail of construction of said cradle.

Similar numerals refer to similar parts throughout the several views.

The cradle, or what may be called a cradle proper or the bed part thereof, is mounted on a base which consists of two parallel planks l0 joined by a board I I, said board supporting a cross board l2 serving as a base for the actuating mechanism generally indicated by numeral l3. Rising from each end of board H is an upright standard l4 including a light-weight extension IS. A cross beam l6, U-shaped in cross section and disposed at the top of said extension I5, is provided with eyes 3 for attachment of a cord I9. Each end member of said cradle proper includes a frame composed of two upright stiles 2|, a horizontal top rail 22 and a horizontal bottom rail 23, the latter being in a spaced relation to the base planks l0. Enclosed by said frame 20 is an outside panel 24 and a somewhat shorter inside panel 25, said inside panel extending downwardly from the top rail to the level of the bottom board 26 of said cradle proper. Thus, the frame and the panels form a hollow end wall of the CPI cradle proper." It'will be noted, however, that said hollow wall is open'from below affording a free space for passage of cords l9 downwardly forattachment to the lower portion of the cradle proper, which will be describedpresently. Ex-' tending between the end members of the cradle,

The space under the bottom board 26 of the cradle proper is utilized fora-drawen3la', slidingly disposed on supports '32. The cords I9, previously mentioned, are attached at their lower end to eyes 33 aifixed to the bottom rails so that the cradle proper swings on saidcords from the cross beam l5;

The actuating mechanism, generally indicated by numeral I3 and described in our application, Serial Number 21,938, consists of an electromagnetic device and includes an arm 34 which, by means of a forked end, engages a cross pin 35 on the under side of the bottom board 26 of the cradle proper. The pin is supported by means of brackets 36. To secure an even swing of the cradle proper and to prevent any bumping of the panels 24 and 25 against beam l6, we are employing two parallel guiding arms 3! pivotally mounted at one end on cross board l2 and hinged at the other end, 39, by means of pintles aflixed to end rail 23 of the end frame 20, as shown best in Figure 3. The dotted lines 31a and 31b in Figure 3 indicate the extent of the swing of said arms from the pivotal connections 38.

Finally, as a means of locking the cradle against rocking, we are employing a rod 4| mounted on the inner side of one bottom rail 30 as best shown in Figures 3 and 4, one end of the rod being controlled by means of a crank 44 mounted on shaft 45, said shaft being actuated by a knob 43, the other end of the rod fitting into a vertical slot 42 in the base plank ID as shown best in Figure 6. The solid lines in said figure show the position of the rod with respect to slot ID in what is the locked position of the cradle. Dotted lines 4la. show the rod in its open position, that is, in the position where the rod is out of slot Ill after having been shifted within a short, U-shaped bracket 46, mounted on rail 30, in the direction of said crank 44.

To conclude the description of the cradle, we

wish to add that numeral l1 indicates a mattress disposed within the cradle proper.

In operation, the cradle, including the frames 20, will be rocked back and forth by means of lever 34 of the actuating mechanism l3, said cradle being guided in its rocking motion by means of said guiding arms 31. 7

It will be understood that some changes may be made in the construction. aboye. described without deviating'from disclosed herein.

What we, therefore, wish to claim is as follows;;;

1. A cradle of the kind described, including a statonar blon base, an u i ht? standard at 1 y g pr g llpiurightjgandargenq the cross beam thereon, cord each end of the base, a crqsgbegine at thfi; of each standard, the cross beamsbeingdisposed parallel to each other and disposed at right the inv ntive principle.

4 afiixed to the lower portion of one end member of the cradle proper to guide the same in a swinging movement to prevent frictional contact of the inner walls of both end members of the cradle proper with the upright standard and the beams thereon.

2. A cradle of the kind described, comprising a stationary oblong base, an upright standard at each end thereof, a cross beam atthe top of standard; and a crenile; proper, comprising two side members and two hollow end members,

both the side and the end members being, at their lower ends, slightly spaced from said base,
